Subject: [PATCH 0/2] mcp23s08 pinconf support

Hi,

Here are two patches for the mcp23s08 driver adding proper support for the
pull-up resistors. The regmap conversion was mainly done to improve the
debugging capabilities, but is also a nice cleanup. Further cleanups could
be done by using regmap's caching instead of the open-coded one.

The patches were tested with a couple of mcp23017 connected to the I²C bus of
an RPi (and modified DT).
